PEAK-TO-PEAK DYNAMICS: A CRITICAL SURVEY
International Journal of Bifurcation and Chaos, 2000This paper is devoted to the study of a particular form of deterministic chaos, here called peak-to-peak dynamics (PPD). When a continuous-time system of order n has PPD, the amplitude and the time of occurrence of the next peak of its output variable can be predicted from information concerning at most two previous peaks.

Peak Oil, Peak Water, Peak Education
New Directions for Teaching and Learning, 2013AbstractThis chapter argues that today's dominant forms of education are insufficient for today's world because they ignore the vast and conventionally untapped resource that lies in the disciplined inwardness that is contemplative life. It then surveys a range of transformative examples that are emerging in the educational movement known as ...

Peak–Peak Repulsion in Ion Mobility Spectrometry
Analytical Chemistry, 2012The space charge effect has an important role in instruments dealing with ion packets and charged particles in gas phase such as the mass spectrometer and ion mobility spectrometer (IMS). It has been shown that the space charge is partially responsible for peak broadening in IMS depending on the ion density.

Peak-to-peak dynamics in food chain models
Theoretical Population Biology, 2003We show in this paper that the chaotic regimes of many food chain models often enjoy a very peculiar property, known as peak-to-peak dynamics. This means that the maximum (peak) density of the populations of any trophic level can be easily forecasted provided the last two peaks of the same population are known. Moreover, extensive simulation shows that

Artificial peaks in energy dispersive X‐ray spectra: sum peaks, escape peaks, and diffraction peaks
X-Ray Spectrometry, 2016Sum peaks, escape peaks, and diffraction peaks are considered artificial or spurious peaks in energy dispersive X‐ray spectrometry. Experimental examples are given, which showed that escape and diffraction peaks can add up to become sum peaks. These artificial peaks are not weak, and great care must be taken to differentiate them from peaks due to ...

A 28 year old man with no medical history was referred to an ophthalmologist with a three year history of gradually worsening visual acuity. His left eye uncorrected distance visual acuity was 20/100, and corrected distance visual acuity was 20/60 (Snellen scale). With direct ophthalmoscopy, we could observe scissoring of the red reflex, and a penlight

Identification and quantitation in conventional 1H spectroscopic imaging in vivo is often hampered by the small chemical-shift range. To improve the spectral resolution of spectroscopic imaging, homonuclear two-dimensional correlation spectroscopy has been combined with phase encoding of the spatial dimensions.
